After downgrade to 6.1, SX OS is only booting into a blackscreen

[Dragon]

Hello,

i have a similar issue as https://team-xecuter.com/forums/threads/155515-SX-OS-not-booting-in-downgraded-6-1, with the exception that using a exfat firmware is not working. As soon as i try to load the custom firmware i just get into a endless blackscreen. Tried with and without Emunand. I also created the emunand new after the downgrade.

Booting hekate works perfectly fine, i also tried booting payload.bin from sx pro manually and from hekate, but both ended in a blackscreen.

I would be really glad for tips to get my switch to work again.


Best regards,

I'm not positive but I'm pretty sure that IF you're downgrading from 6.2 you can't
my understanding is the update 6.2 burnt 8 efuses making the downgrade impossible. IF i'm right you'll just have to wait for the 6.2 fix
go TO STOCK fw until said fix is released.
Maybe someone with knowledge\experience can confirm or correct my comments

Use ChoidujorNX to downgrade to 6.0. To get into Homebrew to do that, use atmosphere or reinx. After you downgrade it should be working fine.

Nope! Actually the downgrade is completely possible and I got mine working, but not on 6.1 on 6.0.

6.1.0 is working fine on hekate, without sleep. Stock OS or SX OS are not bootable at all. I can try downgrading to 6.0.0

Sry , but of course it do not work with SXOS.
Check OFW , my Side is now on sysnand OFW 6.1.0 ( A.M.S 0.7.5 ).
So AMS is not compatible with SXOS.

Also again burnt fuse 7 and not 8. so dont worry.

Later i will test to downgrade it again , to get a normal OFW which every CFW will work . when im finish and it works. I will give Feedback in here.

You downgraded from 6.2 to 6.0 without any issues? How did you update to 6.2? Via Chio...NX or via Nintendo?

better wait 6.2.0 fix =.=

 

[delawaare]

Can you post a link how this downgrade works step by step for noobs like me ?

I have also udate to 6.2.0 and the SX CFW doesnt start.

I think the fix for 6.2.0 firmware from Xecuter will take some months.. There is no Info at all from Team Xecuter how long they will need and if its possible to fix that ! no comments at all !

Its just a guess BUT I had the same issue, updated to 6.2 and lost everything, just a blackscreen on 'bootup'. Once I uninstalled autoRCM using SXOS menu I was able to boot my Switch as normal but only into the OFW. I was told however that this is exactly what 'burns fuses' so i can no longer downgrade.

Anyone know the fastest and easiest way to check the status of my fuses? If my fuses are burned, is there any way to downgrade from 6.2? If my fuses aren't burned then whats the best way to downgrade from 6.2?

I have tried to downgrade from 6.2 before on my PC using TegraGUI and Atmosphere as per this guide http://switchguide.xyz/sdcard.html BUT every time i get to the 'launch atmosphere' step it fails with either "cant be found" or it just hangs up and I have to start from scratch.

Any info would be greatly appreciated cause I've got a feeling this will help a lot of people in the same boat as me. Thanks!

Your fuses are for sure burned if you updated to 6.2 and booted OFW. You can check with Hekate how many fuses are burned. I believe 6.2 has a total of 8 burned fuses.
